Our brains have to analyse and react to hundreds of issues every day, no
matter how big or tiny, at any time. The sheer number of complicated issues
we frequently encounter that require prompt resolution may even be too
much to handle.
The cognitive demands of daily life frequently make such processing logistically
unfeasible, despite the need for time to carefully and methodically assess the
minute elements of our daily work.
As a result, the brain has to create trustworthy shortcuts in order to adapt to
the situations that are full with stimuli. These effective approaches to problem-
solving are known as heuristics by psychologists.
Definition-Heuristics can be thought of as general cognitive frameworks
humans rely on regularly to reach a solution quickly. For instance, when a
student must choose a course of study for college, her instincts will probably
lead her to the one she believes would be the most fulfilling, useful, and
engaging. To help her make a decision, she may also reflect on her secondary
school strengths and shortcomings or even compile a list of advantages and
disadvantages.
It is noteworthy that these heuristics provide good answers, simplify otherwise
complex mental activities, and are often applicable to everyday issues. These
three characteristics are what make a heuristic unique.
Special consideration should be given to psychologist Daniel Kahneman’s
enormous contributions to our knowledge of cognitive problem-solving.
To put his hypothesis in perspective, Kahneman estimated that a person makes
over 35,000 decisions per day! The mind uses “fast” or “slow” reasoning to
arrive at these conclusions.
The goal of the quick-thinking pathway (system 1) is to make trustworthy
conclusions with the least amount of cognitive effort feasible. It functions
primarily subconsciously.
System 2 (slow thinking) needs conscious, ongoing attention to thoroughly
evaluate the specifics of a given situation and rationally arrive at a solution,
whereas system 1 depends on general observations and rapid evaluation
processes (heuristics).
It should come as no surprise that system 1 is used in about 98% of problem-
solving processes given the enormous number of decisions made every day.
To support this quick-thinking route, the human mind must thus build a toolkit
of efficient heuristics.
Algorithms versus Heuristics
Algorithms and heuristics may seem comparable to those who have studied
the psychology of decision-making. But keep in mind that these are two
different ways of thinking.
They are different from algorithms, which are techniques or processes that
eventually always result in a solution.
An algorithm is a methodical process that may be applied consistently to
address a particular issue. Although the term “algorithm” is most frequently
associated with mathematics and technology, human brains employ algorithms
on a daily basis to solve problems (Kahneman, 2011).
It’s crucial to keep in mind that heuristics are broad guidelines that might assist
the mind in processing and overcoming different challenges, whereas
algorithms are a collection of mental instructions specialised to certain
circumstances.

You are utilising an algorithm, for instance, if you are carefully reading every
word of this essay.
However, you are employing a heuristic if you are rapidly scanning each
section for crucial information or maybe concentrating exclusively on the parts
you are unfamiliar with!
According to Pratkanis (1989), heuristics often work when one of five criteria is
satisfied:
When one has little time to make a decision and is presented with an excessive
amount of information
When there is little information available to utilise in making a decision, and
when the decision is unimportant
When the right heuristic just so happens to occur to you at the same time
Consider both the advantages and inevitable disadvantages of using heuristics
while researching them. Because these methods are so common in human
civilisation, it is particularly important to assess their shortcomings.
More precisely, heuristics expose us to certain cognitive biases while
accelerating decision-making processes.
A cognitive bias is an erroneous yet widespread assessment that results from
an irrational thought habit. To put it simply, a cognitive bias is when someone
internalises a subjective view as an objective and trustworthy reality.
Heuristics are trustworthy yet fallible; when using general “shortcuts” to make
decisions to direct one’s reaction to particular circumstances, making mistakes
sometimes is both unavoidable and can lead to more frequent blunders. Take,
for instance, the dangers of incorrectly using the representative heuristic that
was previously addressed. For the sake of cognitive efficiency, the method
promotes grouping events into broad groups based on surface-level traits and
prior experiences; yet, this kind of thinking is also the foundation for prejudice
and stereotypes.
